Warning! As grotesque as health insurance companies are, in theory they are obligated to pay valid claims under your policy. Health sharing ministries can exercise discretion to deny payment because they disagree with your lifestyle choices. Or for any reason or no reason given at all. They are subject to far fewer regulations and audits and in some extreme cases the administrators just pocketed the money.
More and more states are auditing them. But yes it's a faith thing. And definitely not insurance. Works better for tight-knit communities where there is trust.
